1.2 Computer Memory Questions and
Answers Graded A+
What is the purpose of cache memory in a computer system?
✔✔ Cache memory speeds up data access by storing frequently used information closer to the
CPU, reducing the time it takes to retrieve data from the main memory.
How does the size of RAM affect a computer's performance?
✔✔ A larger amount of RAM allows a computer to handle more applications and data
simultaneously, improving overall performance and multitasking capabilities.
What is the difference between volatile and non-volatile memory?
✔✔ Volatile memory, like RAM, loses its data when power is lost, while non-volatile memory,
like ROM or SSDs, retains data even when the power is turned off.
What is a memory module and how does it fit into a computer system?
✔✔ A memory module is a circuit board containing RAM chips that fits into a memory slot on
the motherboard, providing additional memory capacity.

memory, determining how much memory can be addressed and utilized.
What are DIMMs and how are they used in computer systems?
✔✔ DIMMs, or Dual Inline Memory Modules, are a type of memory module that provides
additional RAM to a computer by fitting into DIMM slots on the motherboard.
What is the role of the system bus in memory operations?
✔✔ The system bus is a communication pathway that connects the CPU, memory, and other
components, allowing data to be transferred between them.
What is the impact of memory fragmentation on system performance?
✔✔ Memory fragmentation can slow down system performance by causing inefficient use of
memory space, leading to longer access times and reduced overall efficiency.
What is a memory leak and how does it affect a computer?
✔✔ A memory leak occurs when a program allocates memory but fails to release it, leading to
reduced available memory and potential system instability over time.
